Imagine wanting to have 50 fronts and 10 backs. If you use keep alives, that'll end up being 50 fronts and 50 backs. The overhead of reconnecting shouldn't be much of an issue here, because your front and back machines are probably very close together, and the cost of lookup and reverse lookup shouldn't be much. -- Randal L.
